Why performance matters

Conventional construction vs Isotex ICF

Where traditional systems fall short — and what third-party verified data shows ICF delivers instead.

Conventional construction problems
Thermal bridges at every junctionMortar, timber studs and service penetrations create persistent cold paths — heat loss, condensation and mould follow over the building's lifetime.
No verified lifecycle carbon dataMost masonry and timber systems have no third-party EPD. Specifiers cannot demonstrate embodied carbon performance to planning committees or ESG auditors.
Airtightness requires extra tradesAchieving ≤3 ACH at 50 Pa demands vapour barriers, specialist taping and additional subcontractor resource — at extra cost and programme risk.
Acoustic relies on added layersTimber frame needs acoustic quilt, resilient bars and separate board linings to approach the performance that concrete mass delivers inherently.
Isotex ICF — verified performance data
Thermal bridge-free by designContinuous EPS-graphite insulation wraps every reinforced concrete core — no cold paths. U-value from 0.11 W/m²K. Phase shift up to 14h 06'. Data in EPD S-P-01472.
GWP-total 2.64 kg CO₂ eq./m²EPD S-P-01472: biogenic carbon in 100% recycled wood (−54.7 kg CO₂) nearly cancels fossil GWP (57.3 kg CO₂). Verified by Bureau Veritas, accredited by Accredia.
Inherently airtight — no added tradesReinforced concrete core achieves ≤1.0 ACH at 50 Pa. Locked in at pour, no membrane required. Performance maintained across the 100-year service life.
53–60 dB Rw — no added treatmentISO 10140-3 tested. Concrete mass delivers inherent attenuation. HB 44/15-2 achieves 60 dB — the highest in the range, no acoustic lining required.
